pplication filed December 17, 1923. :Serial No. 681,069.

This invention relates to a. flue construction to 'be located between an upper ice chamber in a refrigerator and a provision holding compartment in-the refrigerator directly below theice chamber, said flue eX- tending through the horizontal partition which separates the two .compartments' or chambers in the refrigerator from leach other. It is a primary object andpurpose of the invention to make a very simple and easily and economically constructed and assembled flue construction for interposition between and connectionof the ice chamber and lower provision compartments of refrigerators whereby air circulation in the refrigerator may be had iniconnection with other i flues between the ice chamber and a side provision compartment, 'and' betweenthe said lower provision compartment and the side Vprovision4 compartment.

An understanding'of the invention'may be had from .the following description, taken in connection with the accompanying drawing, in which,

F ig. 1 is a fragmentary transverse Vertical section through a refrigerator equipped with the flue construction of my invention.

Fig. 2 is a plan view of an element of the construction pror to its being formed into a covering ring for the upper edge portions of lining fianges whichosurround the flue opening in the dividing partition between the ice chamber and'lowcr provision compartment, and

Fig. 3 is an enlarged fragmentary Vertical section through one side of the fiue construction.

Like reference characters refer to like parts in the different figures of the drawing.

Therefrigerator may be of any desir'ed construction and include three compartments or chambers, an ice chamber located at one side and in the upper portion of the refrigerator, a lower provision chamber positioned directly below the ice chamber, and a side provision compartment or chamber having a height equal to the combined heights of the ice chamber and the lower provision chamber. The inner casing of the refrigerator has sides 1 with a Vertical partition 2 dividng the space within the casing and a horizontal partition 3 between one side 1 and the Vertical partition 2 to divide one of the side compartments made by the Vertical partition intoan upper ice chamber 4, a lower provisionchamber ,5, lwhile the side provisionchamber. 6 is located at the opp'osite side of the Vertical indicated in F ig.. 1.' I

Each compartment orchamber is'lined with sheet metal or porcelain covered sheet metal, the lining to one side of thechamber 6 being indicatedat 7..` In the '-provision partition 2, as

chambers, ,the linings 'are covered on their" inner sides with porcelain which is baked theron, makingJM a' very clean and 'sanitaryo l1n1ng.- The provlsion 'chamber 5 has a linusA ingwith sides 8, top 9`and a` back and bottom, the top 9 at its central portion having r an opening therethrough 'with the 'metal turned upwardly to make a continuous lannular flange which passes' through`` a like openingmade inithe partitio'ni'3, thefflange extending a short distance above the upper side of the v.partition.` t The -openings in the partition and top 9 of the lining are elongated with rounded ends and the longest dimension of the` openings is from front to rear,l preferably.

The ice chamber 41 is lined with sheet metal having sides`11 and a bottom 12, a back and top' completing the lining. An opening is made in the bottom 12 similar in shape to the openings in the top 9 of the lower provision chamber lining and in the partition 3, an upturned flange 13 surrounding the 'opening and being located around the upper portions of the flange 10 heretofore described. The upper edges of the two flanges 10 and 13 lie substantially in the same horizontal plane.

A member 14 of sheet metal, shown in Fig. 2, having spaced apart parallel sides with connecting` rounded ends is used and shaped into a form substantially U-shape in cross section, the outer leg 15v thereof being located around the flange 13 and bearing thereagainst, the inward and downward bend 16 lying over the upper edges of the flanges 10 and 13 and the inner leg extending downwardly inside of the fiange 10. The leg 15 is secured to the flange 13v by solder, preferably, and the leg 17 extends downwardly inside of the flange 10 and may be spaced a short distance therefro-m. After the parts are assembled, the lower edge portion of the inner leg 17 may be pressed and curved by any suitable tool so as to bear against the inner sides of the flange 10, as indicated at 18.

yThis, construction of flue is simple and practical. Of course in the complete refrigerator, flue openings are made through the Vertical partition 2 'a'djacent its upper and lower edges, like those shown in my Patent No. 970,672, granted Sept. 20, 1910 in order to provide for a continuous circulation but this is not shown as the invention is directed to the flue construction through the horizontal partition dividing the ice and lower provision chambers. The appended claims define the inventio'n which vis to be considered as comprehensive of all forms of structure coming within the scope of the said claims.

I claim: i i

1. In a refrigerator having an upper and lower Chamber, a metallic lining for the 'upper Chamber having an opening in its bottoml and the metal surrounding the opening being turned upward to form a flange', a lini'ng for the lower chamber having an opening in its top and the metal surrounding said opening being turned upward to form a flange which extends into the first named opening, and a continuous inverted channel member em-bracing and covering the edges of the first and second named fianges.

- 2. Ina refrigerator having an upper and lower Chamber, a metallic lining for the upper chamber having an opening in its bottom and the metal surrounding said opening being turned upward toform a fiange, a lining for the lower Chamber having an opening in its topV and the material surrounding said opening being turned upward to form a flange which enters the first named opening, and a continuous inverted channel member embracing and covering the edges vof both flanges and soldered to the outer fiange, said inner flange being IIonovable relative to the said channel mem- 3. In a refrigerator having an upper and lower chamber, a metallic lining for the upper chamber having an opening in its bottom and the metal Surrounding said opening being turned upward Vto form a flange,

a lining for. the lower Chamber having' an opening in its top and the material surrounding said opening being turned upward to form a flange which enters the first named opening, and a continuous inverted channel member embracing and covering the edges of'both flanges,'said member being soldered to the outer flange and rolled tight to the inner fiange after assembly, said inner fiange being movable relative to said channel member.

In testimo-ny whereof I affix my signature.
